Polarization technique focuses limelight
An international team of astronomers, led by Professor Svetlana Berdyugina of ETH Zurich's Institute of Astronomy, has for the first time ever been able to detect and monitor the visible light that is scattered in the atmosphere of an exoplanet. view more (2007-12-27)
It's raining pentagons
This week's Nature Materials (09 March 2009) reveals how an international team of scientists led by researchers at the London Centre for Nanotechnology (LCN) at UCL have discovered a novel one dimensional ice chain structure built from pentagons that may prove to be a step toward the development of new materials which can be used to seed clouds... view more...

Search for the water of life -- UCL astronomers find water on extra-solar planet
Researchers at UCL (University College London) are part of an international team which has discovered water on an extra-solar planet for the first time. view more (2007-07-12)
Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and marine chemists. view more (2007-09-10)
Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere
Scientists have discovered a bacterial "switch gene" in two groups of microscopic plankton common in the oceans. The gene helps determine whether certain marine plankton convert a sulfur compound to one that rises into the atmosphere, where it can affect the earth's temperature, or remain in the sea, where it can be used as a nutrient. view more (2006-10-30)
Patients may have sweet and effective way to prepare for upper GI endoscopy: an anesthetic lollipop
Researchers at the American University of Beirut Medical Center (AUBMC) in Lebanon have found that administering a lidocaine lollipop as a single-agent anesthetic to patients undergoing an upper gastrointestinal (GI) endoscopy procedure eliminated the need for sedation in the majority of patients. view more (2007-10-17)
New clues to air circulation in the atmosphere
Air circulates above the Earth in four distinct cells, with two either side of the equator, says new research out today (21 August) in Science. view more (2008-08-22)
Say 'goodbye' to back fat rolls
Even as many of us yearn to wear the sheer, body-hugging fashions available today, we are stopped by our rear reflection and the sight of dreaded back fat rolls and lumps. view more (2008-09-12)
Termite insecticide a potent greenhouse gas
An insecticide used to fumigate termite-infested buildings is a strong greenhouse gas that lives in the atmosphere nearly 10 times longer than previously thought, UC Irvine research has found. view more (2009-01-22)
Scientists find solution to solar puzzle
Scientists from the University of Sheffield and Queen's University Belfast have made a unique discovery which will help us understand one of the most puzzling features of the Sun. view more (2009-03-23)
Climate change will affect carbon sequestration in oceans, model shows
The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the effects of global warming. view more (2005-09-08)
Global warming may delay recovery of stratospheric ozone
Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. view more (2009-02-05)
International team of scientists discover clue to delay of life on Earth
Scientists from around the world have reconstructed changes in Earth's ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. view more (2008-03-27)
Features of early Martian environment and presence of water drive search for life forms
olar energy and winds, collisions with asteroids and comets, and changing magnetic fields have all altered the environment of Mars, a planet that may have been able to support life during its history. view more (2009-04-17)
Rivers are carbon processors, not inert pipelines
Microorganisms in rivers and streams play a crucial role in the global carbon cycle that has not previously been considered. view more (2008-12-02)
Cranking up the volume-- Sounds travel farther underwater as world's oceans become more acidic
It is common knowledge that the world's oceans and atmosphere are warming as humans release more and more carbon dioxide into the Earth's atmosphere. However, fewer people realize that the chemistry of the oceans is also changing--seawater is becoming more acidic as carbon dioxide from the atmosphere dissolves in the oceans. view more (2008-09-30)
Venus Express' infrared camera goes filming
An exciting new series of videos from ESA's Venus Express has been capturing atmospheric details of day and night areas simultaneously, at different altitudes. view more (2007-05-08)
Venus mission will hold surprises says U. of Colorado planetary scientist
University of Colorado at Boulder planetary scientist Larry Esposito, a member of the European Space Agency's Venus Express science team, believes the upcoming mission to Earth's "evil twin" planet should be full of surprises. view more (2005-11-03)
Geoengineering: The promise and its limits
Four expert speakers attended an event organised by the Institute of Physics, the Royal Society of Chemistry and the Royal Academy of Engineering on 15 July, at the House of Commons, to address an audience curious about geo-engineering the planet to combat the effects of global warming; the solutions it offers and the concerns it raises. view more (2009-07-21)
Climate catastrophes in the Solar System
Earth sits between two worlds that have been devastated by climate catastrophes. In the effort to combat global warming, our neighbours can provide valuable insights into the way climate catastrophes affect planets. view more (2007-04-27)
